Help with my project using LabView

[Nathan_B.]

Other code can run in parallel but you cannot is any Serial functions in code that is not part of LIFA (because LIFA uses Serial communication).  So, if you want to get information from sensors on your computer while using LIFA, you must get those through LIFA.

Have you looked at the other discussions regarding the SR04?  There are a few different threads that I have posted in.    I believe that the modifications that I made here should work for you.

I saw this thread, but any LIFA controlled option is incompatible with my project.. My arduino will be disconnected from the computer 99% of the time.. it is necessary that it run by itself most of the time. I thought I could use a LabView based GUI to sometimes connect to my arduino remotelly (bluetooth) and get a summary of the sensors. So far I guess I need to move to another option. I've been trying Processing based programs recently, maybe it will work since IDE serial monitor is based on Processing.

LIFA requires a constant connection to the Arduino, it is essentially a slave to the computer/LabVIEW.  If you simply want to connect to it and view data that is being streamed, you could use any serial monitor to do that.  You could very well make something in LabVIEW that acts as a serial monitor and then you would be able to parse the data and plot/store it how ever you like with the convenience of LabVIEW.

In conclusion, it sounds like LIFA is not exactly what you need.

P.S.  I have no idea what "Processing" is (other than the generic word) .
